Set the sampling time as follows.
Set the A/D conversion time as follows.
Be sure to set the FR2, FR1, and FR0, in accordance with the reference voltage so that Notes 2 and 3
below are satisfied.
Example When V
Setting is prohibited because the values do not satisfy the condition of Notes 2 or 3.
2.
the sampling time and conversion time such that Notes 2 and 3 above are satisfied, while taking
the clock frequency error into consideration (an error margin maximum of 5% when using the
high-speed internal oscillator).
The sampling time is 11.0 s or more and the A/D conversion time is 14.0 s or more and 100 s or
less.
Set FR2, FR1, and FR0 = 0, 1, 1 or 1, 1, 1.
